To all whmn it may concern:

Be it known that I, JOHN RITCHIE STE- PHENS, a citizen of the United States, residing at Lake Waccabuc, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Window-Shade Rollers, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to window-shade rollers, and particularly to means for securing a shade thereto; and the object of the invention is to provide an ordinary shade-roller with securing devices by means of which a shade may be properly secured thereto without the use of tacks, nails, or similar devices and by means of which the shade will always be held in proper position, so that it can be wound evenly on the roller.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a longitudinal sectional view of a window-shade roller provided with my improvement; Fig. 2, a plan view thereof, and Fig. 3 a central cross-section thereof.

In the practice of my invention I provide a shade-roller a, of the ordinary spring-roller type, the sprin a by which the roller is turned in one direction, so as to wind the shade thereon, being located in one end of said roller. The said end of said roller is also provided with a plate a and the ordinary ratchet-and-pawl mechanism connected with said plate whereby the rotation of the roller to wind the shade thereon may be stopped at any desired point but these features of construction form no part of my invention, and the roller in itself may be constructed or formed in any desired manner.

In the practice of my invention I form in one side of the roller a longitudinal groove 0 in one end of which I pivot or hinge a rod 1), the pivot or hinge connection of the rod 1) being shown at b and being made in the form of construction shown by means of an eye or ring having a shank 6 which is secured in the plate a at the end of the roller. The

groove 0; at the opposite end of the roller is enlarged and made deeper to form an oblong chamber or recess (L in the bottom outer end of which is secured a spring 0, having a hook member 0 and in the inner end of the chamber a is pivoted a curved arm d, the free end of which is adapted to engage the hook member c of the spring 0, and a supplemental spring 6 is secured in the inner end of the chamber a and adapted to bear on the under side of the arm d when said arm engages the hook member 0 and to force said arm upwardly into the position shown in dotted lines in Fig. 1 when said arm is disengaged from the hook member 0. The longitudinal groove a is also enlarged and deepened centrally of the roller a to form a recess f, in which is placed a yoke-shaped spring-clamp g, the side jaws of which extend outwardly to the surface of the roller, and the clamp g in the form of construction shown is held in position by a staple-shaped device h, passed through the roller, as shown in Fig. 1.

In Fig. 3 I have shown at 'L a part of a window-shade, and in practice the arm d is disconnected from the spring hook member 0 by forcing said hook member 0 backwardly. The rod 1) is then turned out of the groove a and the end of the shade is placed over said groove on the roller a. The rod b is then turned down and forced downwardly into said groove, carrying with it the end portion of the shade, as shown in Fig. 3. The rod 1) is provided in its free end with a loop or eye 11*, and the arm (1 is passed through said loop or eye in the above-described operation and then turned downwardly into the chamber a as shown in the drawings, and is engaged with the spring hook member 0 as shown in Figs. 1 and 2, and this securely locks and holds the rod 6 in the groove a When the rod 1) is swung down into the groove a as above described, it is forced between the jaws g of the U-shaped clamp g, and the rod 1) is thus securely held at both ends and in the middle, and this securely locks and retains the end of the shade in the groove a. If care is taken to secure the end of the shade in the groove a properly, the shade will be evenly held on the roller (1 and may be pulled therefrom or unrolled therefrom and rewound thereon evenly at all times and will not work off the roller longitudinally thereof or press against the sides of a window-frame or other supports between which the roller may be mounted.

In Figs. 1 and 3 I have shown the roller a mounted between supports 7c, secured to a board k but it will be understood that in practice the roller is usually mounted be tween the opposite sides of a Window-frame and at the top thereof in the ordinary man- Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A window-shade roller provided in one side thereof with a longitudinal groove, a rod pivoted in one end of said groove and adapted to lie therein and be swung outwardly therefrom, and means for locking said rod in said groove, comprising a curved arm pivoted in the end of the groove opposite that in which said rod is pivoted and adapted to pass through an eye in the end of said rod, and means for locking said arm in said groove, substantially as shown and described.

2. A window-shade roller provided in one side thereof with a longitudinal groove, a rod pivoted in one end of said groove and adapted to lie therein and be swung outwardly therefrom, and means for locking said rod in said groove, comprising a curved arm pivoted in the end of the groove opposite that in which said rod is pivoted and adapted to pass through an eye in the end of said rod, and

means for locking said arm in said groove, consisting of a spring-hook adapted to engage the free end thereof, substantially as shown and described.

3. A window-shade roller provided in one side thereof with a longitudinal groove, a rod pivoted in one end of said groove and adapted to lie therein and be swung outwardly therefrom, and means for locking said rod in said groove, consisting of spring-clamps sunk in the middle portion. of said groove and a curved spring-arm in the end portion of said groove opposite that in which said rod is pivoted and adapted'to pass through an eye in the end of said rod and a fastening device opcrating in connection with said arm, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 22d day of September, 1905.

JOHN RITCHIE STEPHENS.
